Slingshot

Technology certainly has changed since I was a kid. I can understand the sight and the grip and the wrist brace at the back - not sure about the doodads that flare out to the sides in the front. More pix here.

They're stabilizers. I'm not sure how the physics work, but it's supposed to help keep the bow steady during firing (which is critical to accuracy). Those are actually petite as stabilizers go, check out what they use in Olympic archery: http://www.onlinearchery.org.uk/beginners/part_2_common_bows.html Hunting stabilizers get even more insane.

They work because they are just big weights which make it harder to move the bow. If I remember my college physics it is because it increases the force required to significantly move the object. The heavier something is the harder it is for small movements (think jitters in your hand) to cause movements in the heavy object. This is the principle in camera stabilization rigs such as this homebrew rig.

"Tai-wiki-widbee" is an eclectic mix of trivialities, ephemera, curiosities, and exotica with a smattering of current events, social commentary, science, history, English language and literature, videos, and humor. We try to be the cyberequivalent of a Victorian cabinet of curiosities.
